CVE-2026-116247：pgAdmin 4 服務帳戶憑證被盜用漏洞
CVE-2026-116247 - pgAdmin 4: libpq uses the pgAdmin service account's own password file and client certificate
pgAdmin 4 受 CVE-2026-116247 身份驗證繞過漏洞，任何人可使用服務帳戶的憑證連線至資料庫。
- - 影響：pgAdmin 4 9.19 以前版本。
- - 修補：升級至 9.19 或後續版本，或手動設定密碼檔與憑證。
- - 安全措施：確認環境變數，避免使用預設檔案。
此漏洞允許任何人使用服務帳戶的憑證進行未授權連線，提醒使用者升級至 9.19 以防止身份冒充；同時建議確認密碼檔與憑證設定，並檢查環境變數以確保安全連線。
When a server in pgAdmin 4 had no password file, client certificate or client key configured, or the configured one could not be found, pgAdmin left the parameter out of the connection and libpq fell back to the defaults of the operating-system account running pgAdmin: ~/.pgpass, ~/.postgresql/postgresql.crt and postgresql.key, or PGPASSFILE, PGSSLCERT and PGSSLKEY. In server mode any user could therefore connect to a server with the service account's saved passwords or client certificate, and supplying only a copy of its public certificate was enough for libpq to pair it with the service account's private key. A pg_service.conf entry, or a maintenance database name read as a connection string by pg_dumpall, could bring the same files back for the utilities. The fix gives each of these parameters a value in server mode, the user's own file or otherwise a path that can never be opened, in the connection string, in the environment of the utilities and in the --dbname connection string that ranks above a service entry. Desktop mode is unchanged. This issue affects pgAdmin 4: before 9.19.
